Which Orc hero do you prefer?

Now, back to the topic...
I want to ask what you think about the hero Garuna? I was browsing and noticed her, and realized I've never played with her. Her ability seems questionable: it increases attack if you kill a stack of enemies, but it's obvious that she can only be used in the late game, but there are so many troops there, and the attack won't increase that much... So I launched the game, took her as a starting hero... played a bit, and realized that I'm doing something wrong... So, I want to ask what you think about this hero, how would you develop her (I forgot to mention that she also has ranged attack, which is quite good), and how to use her tactically. My choice in the late game has always been Goshak, so...
